Expert Solution

Step 1: Introduction

Hello! I understand that diving into code can sometimes be overwhelming, especially when you're faced with error messages that might seem cryptic. However, no worries – we'll work through them step by step. Your code consists of the main student file, a utility for the bubble sort, and two headers that structure the functionalities. Let's systematically identify the issues and rectify them in studentMain.cpp.

Follow-up Question

Hi, it is still giving me the same 5 errors as last time even after modifying the code. I tried reordering #include "student.h" and #include "bubble.h" in studentMain.cpp but it gave me more errors. Is this happening because I am compiling with the wrong command, I am compiling it all together like this: g++ studentMain.cpp bubble.cpp bubble.h student.h grades.txt. I have the modified code below and a reminder that I can only edit the code in the studentMain.cpp file:

//studentMain.cpp

#include <stdio.h>
#include <stdlib.h>
#include "student.h"
#include "bubble.h"

int main()
{
// Create an array of 19 student pointers
student *students[19];
// Allocate space for each student in the array
for (int i = 0; i < 19; i++) {
students[i] = (student *)malloc(sizeof(student));
}
// Read in the data from the file
FILE *fp = fopen("students.txt", "r");
if (fp == NULL) {
printf("Error opening file\n");
return 1;
}
for (int i = 0; i < 19; i++) {
fscanf(fp, "%s %s %d %d %d", students[i]->first, students[i]->last, &students[i]->exam1, &students[i]->exam2, &students[i]->exam3);
// Calculate the student's mean
students[i]->mean = (students[i]->exam1 + students[i]->exam2 + students[i]->exam3) / 3.0;
}
fclose(fp);
// Sort the students using the bubble sort algorithm
bubble(students, 19);
// Find the mean, minimum, maximum, and median of the grades
float mean = 0.0;
float min = students[0]->mean;
float max = students[18]->mean;
float median = students[9]->mean;
for (int i = 0; i < 19; i++) {
mean += students[i]->mean;
}
mean /= 19.0;
// Print the class statistics
printf("CSCE 1040 MEAN %.2f MIN: %.2f MAX: %.2f MEDIAN: %.2f\n", mean, min, max, median);
// Print the student averages
for (int i = 0; i < 19; i++) {
printf("%s %s %f\n", students[i]->first, students[i]->last, students[i]->mean);
}

// Free the allocated memory for each student
for (int i = 0; i < 19; i++) {
free(students[i]);
}

return 0;
}

//bubble.cpp

#include <stdlib.h>
#include "student.h"

void bubble(student *array[], int size)
{
int x;
int y;
student *temp = NULL;

for(x = 0; x < size; x++) {
for(y = 0; y < size-1; y++) {
if(array[y]->mean > array[y+1]->mean) {
temp = array[y+1];
array[y+1] = array[y];
array[y] = temp;
}
}
}

return;
}

//bubble.h

void bubble(student *array[], int size);

//student.h

typedef struct student_info{
char *first;
char *last;
int exam1;
int exam2;
int exam3;
float mean;
